Tachys parvu/us, Dej., at Horsell. — Amongst a number of common Coleoptera 

 captured on the wing to-day — the first really fine day this year — I was agreeably 

 surprised, on emptying the bottle in the evening, to find a specimen of Tachys parvu- 

 lus, Dej. It has quite recently been recorded from the New Forest (Ent. Mo. Mag., 

 xxxviii, p. 65).— G. C. Champion, Horsell, Woking : April 13th, 1902. 



Sirex juvencus, L , in Paternoster Row, London. — On the Eth inst. a very lively 

 9 of Sirex juvencus was caught in an office in Paternoster Row ; it is still living. 

 Probably it had emerged from a continental packing ease. — R. MoLachlan, Lewis- 

 ham, London : April 17th, 1902. 



A black variety of Hoi ocentr opus picicornis, Steph. (Trichoptera) from South- 

 West Ireland. — Col. Yerbury gave me a small black Trichopteron from Parknasilla 

 (Co. Kerry) which he took on July 13th, 1901. At first sight it resembles a small 

 Silo or large Bercea, but examination proved it to be a Holocentropus, with no 

 structural characters to distinguish it from H. picicornis. The wings are totally 

 black, with the pubescence of the anterior slightly rusty (which will probably in- 

 tensify with age), the antennae without annulations. Mr. Morton agrees with me 

 that the appendages (it is a £ ) show no difference, and Mr. King informs me that 

 he has not met with a similar variety in the Killarney district, where he has done 

 much collecting. As is so often the case in parallel instances only this one example 

 was taken : in fact, Col Yerbury brought only two specimens of Trichoptera from 

 the district, this and a (J of Sericostoma personatum, Sp. In my " Monographic 

 Revision and Synopsis," p. 403, I say of IT. picicornis that some examples have the 

 anterior wings " nearly black, without markings." I possess no such old specimen 

 now, and feel sure the words were not intended to apply to so black a form as that 

 noticed above. — Id. : April 5th, 1902. 



A few Trichoptera from West Cornwall. — It may be well to place on record the 

 following species captured by me between May 20th and June 6th, 1901 : — 



Leptocerus cinereus, Curt., Lizard ; Adicella reducta, McLach., Lelant, Porthon- 

 stock ; Dipleclronafelix, McLach., St. Ives, Lelant, Porthonstock ; Philopotamus 

 wont anus, Don., St. Ives ; Wormaldia occipitalis, Piot., St. Ives, Lelant, Porthon- 

 stock ; Plectrocnemia geniculata, McLach., St. Ives ; Polycentropus favomaculatus, 

 Pict., Porthonstock ; Tinodes wceneri, L., a small form, Lizard ; T. assimilis, McLach., 

 Porthonstock ; Rhyacophila dorsalis, Curt., St. Ives ; Ayapetus fuscipes, Curt., St. 

 Tves, Lelant.— W. C. Boyd, Cheshunt : April, 1902. 



Historical Notes on Lyca-na Acts in Britain. — I have read, and with interest, 

 Mr. Dale's " Historical Notes on Lyccena (Polyommatus in my day) Acis" in the 

 April No. of the Ent. Mo. Mag., p. 76. I see my name mentioned as having taken 

 Ads in Gloucestershire as follows : — " Two at Lower Guiting, on the Cotswolds, by 

 the Rev. J. Greene in the beginning of July, 1849 " (Zoologist, vol. x, p. 3494). 

 The capture is correct, but the date of the year and the month of the capture are 

 alike wrong. The reference to vol. x of the "Zoologist" (published 1852) is 

 " List of Lepidoptera on the Cotswolds, Gloucestershire," written and sent by
